This issue is still preventing me from properly using the drive. I’m going to do some more sustained r/w and heat testing to see if it will cause issues.
Update 1: formatted and installed Ubuntu 22.04 on it as a benchmark. I did about an hour of configuration (mostly messing around trying to heat it up) before I suspended it and on wakeup was met with drive write errors and a full system crash. Took it apart and it didn’t seem too hot at all. My theory is the sustained read on system resume caused this one.
I’ve located a friend with a Thunderbolt 3 port on their laptop (14” Lenovo Yoga with an 11th gen i7), and they’re willing to do some writing in documents on the drive, so I’m handing it over to them for the next test.
